Turbo blow off valves that won't fail you at the worst possible time
The blow-off valve is a safety device that prevents engine damage in the event of an over-boost. It allows pressure to be released from the intake tract, preventing excessive airflow into the compressor and causing it to stall or over-rev.
Overboosting can cause serious engine damage if not addressed immediately. The stock diverter valves are susceptible to failure and often do not operate properly when needed most.
We offer high-quality blow-off valves with upgraded features such as billet aluminium construction for improved durability, stainless steel spring retainers for increased corrosion resistance. These larger diameter springs remain torsionally rigid at higher temperatures than standard springs.
Leading engineers design our products with years of experience developing products for professional racing teams across multiple motorsports disciplines, including Formula One, NASCAR, IndyCar Series, NHRA, IMSA WeatherTech SportsCar Championship, WEC (World Endurance Championship) and more.
Our range of electronic blow off valves will make your car faster and won't cause any extra noise because it uses an electronic control instead of a spring-loaded diaphragm like most other valves do. You'll also need less piping than you would for a regular BOV, so installation is easier too.
Everything you need to augment your turbocharger and blow-off valve
Prospeed stocks a wide range of accessories and components for your blow-off valve and turbocharger that deliver you valuable boosts on race day, including:
- BOV adapters and delete plates: By using a blow-off valve adapter, you can turn your BOV into a more subtle venting system that uses the pressure from the intake manifold to release air out of the engine bay instead of letting it go through the BOV itself. This makes much less noise and enables you to control when your vehicle releases its excess pressure without sacrificing performance.
- BOV accessories: We have all of the parts you need for a successful installation, including hoses and clamps. Our BOV accessories include everything from silicone hose kits that improve boost response time by up to 30 per cent to aluminium fittings that prevent leaks caused by vibrations at high speeds or under heavy load conditions. Whether you're looking for replacement BOV gaskets or tools like our billet blow-off valve tool kit, we've got what you need in stock and ready for fast shipping.
- Wastegate actuators: Internal wastegate actuators are used to control boost pressure in turbocharged engines. They are highly complex components that require careful installation and calibration. Installing it correctly isn't always easy either. If done wrong, your car could suffer from lag or boost creep issues that could cause engine damage later on down the road if left unchecked. Let the team at Prospeed help with the proper wastegate actuator for your right and expert advice on installation and calibration.
